Many items within the Library’s collections deserve to be
highlighted. This may be because of their historical importance,
uniqueness, beauty, fascinating content, or perhaps their personal
associations. In this special collection within the Cambridge
Digital Library we will draw together books, manuscripts and other
items from across our collections that are especially significant.
Many of them have been displayed in Library exhibitions in the past
– now they can be accessed at any time, from anywhere in the world,
and browsed cover to cover.

Cambridge University Library is pleased to present the first
items in its Foundations of Science collection: a selection from
the Papers of Sir Isaac Newton. The Library holds the most
important and substantial collection of Newton's scientific and
mathematical manuscripts and over the next few months we intend to
make most of our Newton papers available on this site.

The notebooks kept by the soldier-poet Siegfried Sassoon
(1886–1967) during his service in the British Army in the
First World War are among the most remarkable documents of
their kind, and provide an extraordinary insight into his
participation in one of the defining conflicts of European
history.
